Kogel ceramic bearing balls are smoother and rounder than any steel bearing because of their material properties
Silicon Nitride can be polished much smoother than steel. Also, it does not compress as much as steel, leaving the contact points with the bearing races very small and not squashed like a tennis ball under load. Compressing any material under load and trying to roll it will cause unnecessary drag. When we talk about wheel bearings - 2 bearings in the front, 2 in the rear and 2 in the freehub, it is worth considering what you want from your seals. The Kogel Bearings road seals are built to create the lowest friction we can get out of a sealed bearing. The cross seals are built to have the best protection against the elements. We always encourage Cross seals for longevity however you can pick whichever best suits your riding style and you get the same Kogel warranty.
